Patents by Inventor Barry John Muldrey

Barry John Muldrey has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Analog push pull amplifier-based physically unclonable function for hardware security
    Patent number: 10211993
    Abstract: An authenticating circuit includes a first and second challenge vector input, a first and second highly variable process-dependent circuit and a logic circuit. The first highly variable process-dependent circuit receives a first vector from the first challenge vector input and generates a first output that is a function of the first vector and at least one process-dependent feature of a component of the first highly variable process-dependent circuit. The second highly variable process-dependent circuit receives a second vector from the second challenge vector input and generates a second output that is a function of the second vector and at least one process-dependent feature of a component of the second highly variable process-dependent circuit. The logic circuit generates a response output that is a function of the first output and the second output. The function operates so that the response output is independent of environmental conditions of the authenticating circuit.
